[Time Travel + Substitute Marriage + House Fight + Medical Skills + Wife Chasing Crematorium] An imperial edict made the general's mansion and the prime minister's mansion, who had a blood feud, become in-laws. In order to get clues to return home, Lin Nanxing, a surgeon from time-travel, agreed to marry him. As a country bumpkin who was brought back from the countryside to be married by the general's government, Lin Nanxing faced her natal family who was full of calculations against her, her husband's family who were full of disgust and hatred for her, and the circle of ladies who looked down on her. On the wedding day, when all the noble ladies in the capital were grieving that their sweethearts would be defiled by such a country bumpkin, shocking news came from the Prime Minister's Mansion. Lin Nanxing, who was to become Shen Yushi's wife, asked to marry Shen Yuyun, who was killed by the general, and vowed to remain a widow for him for the rest of his life. Ignoring the shock of everyone in the hall, Lin Nanxing looked at the Prime Minister and his wife sincerely, "The imperial edict is that the daughter of the General's Palace and the legitimate son of the Prime Minister's Palace will be married. The younger one is willing to marry the Second Young Master Shen, Shen Yuyun." Shen Yushi didn't understand why the two of them were originally in love, but because they didn't catch up with the wedding day, the person they loved became the widow of his long-dead brother. How willing he was! "You are my wife!" In order to get the key that might be in the hands of the Prime Minister's wife, Lin Nanxing resolutely abandoned the original marriage partner and decided to marry the other party's dead son. Who would have thought that the key was actually in the hands of the original husband! What else can be done? I just tried my best to conquer him!
